I have an Asus Maximus III Gene (the mATX one!) and I bought memory (OCZ Platinum) that was not listed on the compatibility list with Asus. Maybe I got lucky... or maybe that's just an overly conservative (or just out-of-date) compatibility list.
Anyways... you can find people have problems with EVERY type of RAM if you look hard enough. What sort of return policy will you be dealing with?
The ASUS compatibility list is very much out of date, it did however really scare me that it wasn't even on Corsairs compatibility list. But I hope I get lucky
Luckly I had a talk with a nice guy where I bought all the hardware and he would be willing to get me a refund (or an exchange) if they didn't work out, but I really hope they do... Who can pass up nice read RAM for a nice red ROG ASUS MB
